ATSG Tech Manual JR403E

This ATSG Medium Duty Truck Diagnostic Code Manual has been produced in order to help the diagnostic technician retrieve diagnostic trouble codes from tilt cab trucks such as the Isuzu NPR, Chevrolet Forward, GMC Tilt master, Mitsubishi Fuso, Nissan UD and various Hino models. This manual also contains the code retrieval manual process for the Ford and International LCF Series trucks equipped with the 5R110W transmission. These trucks can be equipped with various transmissions such as the JR403E Electromatic, the Aisin Seiki 450-43LE or the Aisin 6 speed transmission. There is also a reference to the Mitsubishi Fuso manufactured Sterling trucks.

Since most shops do not have a dedicated scan tool to retrieve codes, this manual contains the manual code retrieval process for the above mentioned vehicles as well as code definitions. It also contains the relearn procedures that are necessary for proper transmission operation.
